Research On Generation And Optimization Of Reserved Bus Routes

With the rapid development of urbanization,informatization and science and technology,the concept such as "green transportation and public transport priority" continued to deepen.Throughout the most major cities of China,city public transportation service level is still in the lower level,this problem has been paid more and more attention,convenient,comfortable,fast,fare costs become the factors considered when people travel.Under the existing public transport system,it has become the inevitable trend of urban traffic development to develop a diversified,personalized and service-oriented traffic trip oriented by residents’ travel demand.This article through to introduction and analysis of the current urban secondary public traffic system,especially the opening of the custom in many cities of the present analysis of bus,puts forward the new idea of bus travel booking theory,and carries on the further research.First of all,the paper concludes the concept and composition elements of the reserved bus,and systematically and comprehensively analyzes the factors which influence the normal operation of the reserved bus,summarizes the advantages of the travel mode of the reserved bus.On this basis,the overall concept of the reserved bus system is given,the components of the system are analyzed,and the process of booking the bus system is defined.Then,according to the characteristics of the reserved bus and the travel demand of the passengers who will book the bus,we determine the general method of route generation of the reserved bus,which includes analysis and reservation of bus travel demand data,determine the docking site constructing route generation model,optimal path,path set for the initial line generated by A* algorithm.Then continue to optimize the line of initial set generated,considering operating costs and passenger travel cost and social benefits,we can establish the route operation standard model with minimizing thelinear weighted sum of the cost of operation and time,and the model is solved by particle swarm algorithm.In order to ensure the rationality of route optimization of the reserved bus,an evaluation system of reserved bus route network is established.Finally,through the random generation of urban resident travel demand in the road network,the feasibility of the reserved bus implementation and the rationality of the reserved bus route network generation and optimization model are verified by examples.Through this study,the paper clarifies the potential advantages and market value of the reserved bus,it makes a certain contribution to the attraction of residents travel car shift to public transport,and have a positive and far-reaching significance to promote the diversification of public transport services.
